TLDR
It is reported that colloidal nanosheets of a Dion–Jacobson type layered perovskites, Ca2Nb3O10, adopt a LC phase with a mesoscale structure by condensation after the conventional preparation of the nanosheet colloid.Abstract:
Three nanosheets to the wind: A liquid‐crystal phase in the condensed colloids of semiconductor nanosheets of a layered perovskite Ca2Nb3O10− was synthesized and characterized. Their properties and functionalities are tunable for further fundamental studies and potential applications as smart soft materials.read more

The effects of shape on the interaction of colloidal particles
TL;DR: In this article, it was shown that colloids in general are apt to exhibit considerable deviations from Raoult's law and that crystalline phases retaining a fair proportion of solvent may separate from concentrated solutions.

Perovskites by Design: A Toolbox of Solid-State Reactions
TL;DR: In this paper, a set of soft-chemical reactions of layered perovskites have been reported, and they can be classified into sets of similar reactions, such as ion exchange and intercalation reactions, and more complex metathesis reactions replace interlayer cations with cationic structural units.
